The direction of sand movement along the Carmel River State Beach was qualitatively determined by diving observations, a bathymetric survey, wave refraction diagrams and a sediment size analysis of 18 samples. The primary source of sediments for the beach appears to be the Carmel River which flows only seasonally. Sedimentary material is introduced into the bay after winter precipitation provides a sufficient amount of run-off to warrant the opening of the river mouth by bulldozer. The fine sedimentary material is lost offshore and the coarser material is either redeposited on the beach or is carried south with the littoral drift and deposited at the nodal point in the sand transport pattern. This node is located on the northern edge of the head of the Carmel Submarine Canyon. Winter storms probably induce slumping or gravity sliding and much of the material is carried to deeper water by the canyon.
